How to compile an iOS application correctly?

Question

Objective-C

Good day! I'm finishing my project, now I'm thinking about how to compile the application correctly ... It needs to work on iOS versions 7.0 and higher. So, if I do not specify anything in the deployment target, will the compiled project work under 7.0?
Version xCode 6.4 and iOS 8.4 SDK.

Answer 1

If you do not specify anything, then 8.4 will be set by default. So in the project settings, namely in the deployment target, specify 7.0, this should also appear in the settings of your target
